I'm a believer in trying to answer an OP question without attempts at pushing people to do something different from what they asked about.
I'm with you, OP--I will use 72-bass and will also use 48-bass, but 60 is perfect when one wants to go light. It gives you chords for all scale notes while being a smidge lighter than a 72-bass in a way can indeed make a difference.
Will we assume you are talking about a box with 26 treble keys? Asking because you mention your 32-bass, and those are not all 26 treble. But assuming you do mean 26, yes, there are 26/60 MMs out there. The caveat is that if by "decent brand" and "good internals and reeds" you mean Italian-made or the old West German Hohners . . . the West German Hohners didn't come in that configuration, and Italian will cost you. Inflation on prices for new Italian accordions has skyrocketed. I have never seen a vintage Italian 26-key in a 60-bass configuration.
Here are some Italian companies that make MM 26/60s. Well, I should say, up until the pandemic. It's unclear what kind of output has been going on since then. The smaller sizes don't seem to be appearing in dealer inventories the last couple of years--Current new output seems to be emphasizing the big models they can charge big money for. I can't tell whether the constriction is permanent or will pass. Anyhow:
These accordions are all over 3,000 euro in price.
Serenellini makes a 26/60 MM, usually they are the wood-chassis models. I think with hand reeds.
Beltuna makes a 26/60 MM, they usually are the French-polished the stained/painted wood finishes, but I've seen black too.
Bugari makes a 26/60 MM but you may have to order it because the 26-keys that appear in dealer stocks are usually 48. But they do make 60.
-----For example, here is a Serenellini 26 60--the first is in black. The second is the wood-chassis "Teddy" model, which I've seen in 26/60 and 26/48. The Serenellini would probably be an order, I don't see any in stock anywhere:

-----Here is a Beltuna 26/60 listed by a store in France--priced at nearly 3700 euro--not in stock, listed as a special order. If you order one, order it specifying without the "arty" paint job or solvent on the bellows. I have one purchased five years ago from a US dealer at a price lower than this, and the fumes coming off the bellows are still ghastly, front and back. Maybe it's glue, but whatever it is should be banned on health grounds. The sound and response of the reeds is wonderful, but it's sitting in the case until I can have the bellows replaced:

-----There is also of course the eye-wateringly expensive 60-bass MM 34-key Saltarelle Clifden:

-----OTOH, there are Hohner Bravo 26/60 models available out there in red or in black at much lower prices. It's not uncommon to need to take your brand-new Bravo to your local tech for fine-tuning adjustment or reed voicing/reed gapping adjustment fresh out of the box. (News Flash: This is also true of brand-new Italian accordions.) After some years the springs operating the bass buttons and piano keys in the Hohner Bravos can tend to wear out, but springs can be replaced. I'm leery of the big models with more reed banks, buttons, and switches, but I've found the little MMs to be responsive, playable instruments that can serve you well for folk music.
-----If you get on with the slimmer keys, there is also the MM Weltmeister Rubin 60-bass model with 30 treble. Chassis dimensions and weight are the same as a 26-key. A unique and delightful option provided you don't mind slimmer keys. Welt is another cheaper brand whose small MM models I have historically liked for folk music--that is, at a certain price point. The prices of these are getting up there in a way I find dismaying given they have plastic reedblocks and a plastic bass mechanism. Sadly, post-pandemic inflation of accordion prices seems to be the way of things across the board. Here is an example from a Thomann listing--I'd go with a reputable individual dealer, but this is as an example:
Piano Accordion 60 Basses, 30 Treble keys, 2 Reed ranks on the treble side, 3 Reed ranks on the Bass side, Tonal range: G to C, 3 Treble registers, Keyboard with 18 mm key width, Dimensions (W x H x D): 33.2 x 18.2 cm, Weight. 5.6 kg, Colour: Red,...
