PLO50 KK53ds 3bet pot too weak to slowplay?

So very loose player iso raise limper from BU and I go for 3bet from SB. Plan is to stack off to 4bet. I just wonder if this hand is reasonable to slowplay on flop as this opponent tend to be way too stab happy. I would just pot flop if I didnt have bd fd also. Plus I think 53 is also kind of nice component interacting with board so some of the straightening cards are going to hit me also somewhat often.

Well as I post this it might be indicator it didnt end nicely this time
