Could you provide some evidence, even if anecdotal, rather than vague comments like "not advisable" and "unexpected results..."? If you spend some time reading the threads I've collected and linked above, you will see that there are many, many, many people who have done this with different airlines including UA and AC. In my own personal experience, (and others on FT) after check-in with UA, it is easy to change the FF# yourself on the united.com website or at a United kiosk and then have the BPs reprinted either at kiosk or in the lounge or gate or whatever. I have examples of this on the current trip I am on to South America and the miles have already credited to A3. I even kept original check-in BPs that have my AC*G and then the next ones with A3 that still show premier access, seating group and seating assignment (moved to E+ at check-in).
In the case of AC, their upgrade policy even *specifically* states that flyers may change their FFP after the upgrade is confirmed (at the gate for instance) In reviewing threads I point out the following posts:

My upgrades have always cleared with UA MP # for FF credit. AC SE # for my SE benefits.
AC gets the lionshare of my fare instead of UA.
Which at least answers the matter of the matter of the FQTV and FQTS fields for the OP, who I would guess is asking principally about AC flights (or at least partially about AC flights)

And according to that quote, it seems that you definitely can be waitlisted for an upgrade, change your FFP# during OLCI, and still be on the list!
This same thing happened to me a few months ago in CUN and AC/AE customer service has been unwilling to correct the agent's mistake. I'm currently pursuing the matter through *A.
Air Canada specifically instructs that nominees (at the least) can change their FFP AFTER receiving an upgrade at the gate.
I would suggest calling AC and making every attempt to get the FQTV and FQTS fields properly filled. Your travel agent may also be able to make the changes. It should be noted that some members of *A (SQ) even list 2 FF#s on the BP.
