Somewhat interesting ICM spot vs unknown because I suck at assigning ranges to randoms

Poker Stars $6.71+$0.29 No Limit Hold'em Tournament - t20/t40 Blinds + t4 - 5 players -

BB: t221 M = 2.76
UTG: t282 M = 3.52
CO: t1185 M = 14.81
Hero (BTN): t903 M = 11.29
SB: t409 M = 5.11

Pre Flop: (t80) Hero is BTN with ??

1 fold, CO raises to t120, Hero ???

Well, we can right away tell from his opening size that he likely is quite bad. Unfortunately I have total 6 hands on him, only stat being VPIP 66%. However, since he doubled, most people tighten up after that so actually giving him range here is somewhat tricky. Probably something like A8s+, ATo+, 77+, KQ. Even that range may be too loose on average.

There also lies a problem in stack sizes, clashing would be bad since winner of the pot would have ~2k+ chips at which point there is very real diminishing return on chips. (of course, the ICM tax isn't that high in 6 max since these are so top heavy). Of course, him being random he likely don't have understanding of ICM so he will call a shove too loose with some hands.

So, what shall we do here with:

AA (AA is probably only one I could see flatting here)
KK-JJ, AK
TT,99, 88
AQ
worse hands?

What do you think? Any comments will be helpful, I have very hard to putting ranges to players.
