He also didn't describe him as a calling station donk...
If I assign V1 25.2% range from UTG, he doesn't have much of anything that would improve from crap to low equity slightly-better-than-crap hand.

6 will improve all his range with 8 in it and of course 66, which literally doubles his equity to 28.5%, and giving him sufficient implied odds. And if it also turns a backdoor flush draw, it adds even more equity to his range.
9 would turn his T8 (bottom of his range) into OESD, and again there is the flush draw scenario.
Anything above a 6 will essentially improve his range significantly, whereas anything below that will completely miss his range and he will simply fold to a bet, and we gain nadda and had given him a free card to destroy us with RIO.
And let's not forget that he will gain bluff equity as well.
Bottom line: your plan is no bueno.
