So you have collisions. ("Does Y mean "yank"? Or does it now mean "to"? Well "to" can't be T anymore, because that's now the motion up command.")
So you have to either remap everything back to qwerty positions, and learn the new mnemonics, or keep the letter associations the same, and give up on the clustered motion commands.
I'm thinking it's probably better to do the latter, but I'd love to hear from vimmers that use non-qwerty layouts.
I find that remapping shortcuts is generally not worth it. Yeah, undo/cut/copy/paste are weird and that sucks, but it's better than fighting every application you ever use, on every machine, including machines you SSH into, until you die.
For gaming, on the other hand, mixed up keybinds are intolerable. I just switch back to QWERTY for that.
So even if I ever did make the jump to Colemack or Dvorak, I'd probably keep those mappings to the same physical keys. Working in vim, I'd just use my "arrow" keys rather than the native motion keymappings.
I also try to avoid using them in the first place (instead using w/b/f/t/n/etc), but sometimes it's faster to just tap the key a few times rather than "formulate a plan" to reach my target
A 60% (no arrow keys) has 61 keys (ANSI) and the next “bigger” one, a 65% has 67 keys and usually already arrow keys.
Is it some non-standard ergo mech build?
Basically this. Not really ergo, other than being ortholinear and having space between the resting positions of my hands.

I would definitely advise against remapping vim bindings. The first is because if you ever has to use vim on a non-colemak machine, figuring out the keys will be very painful. Secondly because vim has influenced a lot of other programs (man, less, gvim, etc) and most of them are much harder to rebind if they even support it at all.
