TueS 29 to 27.5

I have a Tues 29 frame. I want to build it into a full 27.5 park bike with a 27.5 bomber 58.

My only concerns is the geo changing and the height of the BB becoming too low if I do this. I know I can’t bring the rear height of the bike up, but I’ve heard that there’s some lower headset spacers on the market that could raise the front end and account for some of that wheel drop.

Has anybody done this? Would it just be easier to get rid of the 29er frame and pick up a dedicated 27.5 frame?
