Yes, that shouldn’t be too bad.
I went nuts and did humbucker coil splits, out of phase and serial (on an HH with 2 vols & 2 tones). The coil split doesn’t really sound all that much like single coil to me. Just a bit quieter. The series switching sounds good (fuller, brighter?) If you use crocodile clips, or temporary connectors (e.g. Wago clips) you might be able to try different re-wire options before committing to soldering.
I used Bourne https://www.bourns.com/docs/product-datasheets/PDB183-GTR.pdf which look similar to yours. The terminal pins were pretty small and hard to work with. The CTS ones are supposed to be easier, but I don’t think that they do push-push.
Have fun
Good idea to go for push-push over push pull. I have them on different guitars and push-push is quicker and easier.
I haven’t found any manufacturers that do push-push with triple pole double throw, though.
I also put a free-way pup selector on a strat copy, which is an alternative to switchable pots. https://sixstringsupplies.co.uk/collections/guitar-switches/brand_free-way

See what you mean: the Yamaha Revstar doesn’t have Yamaha on the headstock, but does have the tuning forks.
But other Yamahas don’t have the tuning forks but do say Yamaha. Eg. https://uk.yamaha.com/en/products/musical_instruments/guitars_basses/el_guitars/sg/index.html
I think there was a period, pre Revstar, when motorbikes had the tuning forks but none of the Yamaha guitars did.
