Well, mine had the painted rear end but basically, you are trying to make the shock eye-to-eye length 4 or 5mm shorter. Judging by the proportions of the rocker, that’ll move the seatstays bridge in by 1.5x that, so at least 6 or 7mm. If you don’t have that much clearance at full bottom out just now, it won’t work. Also have a look at the bottom link under the seat tube at full compression, there’s not much clearance there either.
I did run an angle set for a bit, which helps and always ran the sag on the rear a bit more than Turner suggest, typically 17-18mm on the shock shaft, which also helps. If you don’t have forks already longish forks, i.e 150 or 160mm travel will also work well to keep things a bit slacker and it doesn’t feel at all unbalanced with 160mm 36s on the front.
