110edo

110edo has a step size of 10.909090909091 cents. It reinforces 55edo with the same 3, but a flat 5 instead of sharp 5 (in patent val), it also gains a new 7, 11 and especially 13, now quite accurate. But if you want the meantone system back you can still use every other note, experiencing the wonders of generic meantone with non-standard 7, or the new 7, or whatever you choose. It's wonderful either way.
