As a medium sized human (5'-8"), I've become a convert to the cult of the mullet. With similar geometry, I am finding that I'm able to corner much better than in a full 29 setup, and also find that it's easier for me to ride "loose". While mullet setups seem to really be catching on in DH racing, there are very few trail/enduro bikes offered with mullet setups, so people interested trying this out need to do a conversion.
Someone posted this calculator on Vital, which makes it easy to check the impact of mulleting a bike on the geometry: https://geo.syn.bike/
A simple rule of thumb is that swapping like for like (change the 27.5mm fork for an equivalent travel 29mm fork, or put a 27.5 rear wheel on a 29er without changing fork travel) will result in slacking out the head and seat tube angles by about 0.9 degrees, and either raising (27.5->mullet) or dropping (29->mullet) the BB 12mm.

I'm no longer actively updating this unless I see a bike that tickles my fancy, but you can PM me and I'll give you editing permissions if you want to add something.
Hope this helps someone. If you know of a factory option, or a potentially good conversion, let me know and I'll update this. My definition of "not too screwed up" geometry is probably something like 63.5-64 HTA, 76-77 STA, 335-345 BB height.
