Unfortunately this gets exploited by your opponent betting all his top pair and overpairs to a sizing that's less than 75% pot, which an opponents likely default strategy is going to be unless you play live. Donking into the preflop raiser when he has cbet is extremely hard to balance. Often on this board the preflop raiser is going have a pretty strong range when you get to the turn this way. Also if you are going to try this strategy it only really makes sense if you actually start the bluff (you are choosing this hand to float with and then bluff on the turn) with some equity or it's just going to be -ev in the long run, ie. why reverse float this hand when you could reverse float 98s where you have a backdoor flush as well as a backdoor straight draw.

Edit: also it makes more sense to bluff turns where a 4 or a 2 comes off as it's not as likely that your opponent cbet with a 4 or 2 and you can have all the 4's or 2's depending on what the preflop actions were or even what kind of game this was. Also floating isn't something that you should be aiming to do, it is more a combination of how the board runs out, how many bluffs your range has and how much equity your range has and so forth.
