One of the things to consider is, as of this past November, Wyndham restructured their VIP program, and eliminated unlimited housekeeping. This was one of the big benefits of the VIP program. VIP levels used to start at 400k retail points for Silver, 700k for Gold and 1 million for Platinum (used to be 300k for Silver, not sure when that changed), but as of November it is now 500k for Silver VIP, 800k for Gold and 1.1 million for Platinum (there's also a lower level bronze which I dont know anything about). New VIP owners after November 12, 2020 no longer receive Unlimited Housekeeping. It's unclear that this process which has been described here would allow for a transfer of that unlimited housekeeping benefit or not. It's unclear if it's tied to the contract, or the owner, or some combination. This isn't something you could call Wyndham to clarify either, because you are in effect trying to skirt the rules by using an undocumented loophole.
Regardless, if you buy 150k of anything off the resell market, even if it's part of an existing VIP owner's portfolio, if you transfer if to you, it will not have any VIP status, because it's below the threshold for any VIP... if you were an existing VIP (above at least 400k points prior to Nov 12, 2020), and were able to buy, say 400k points using this method, you, in theory should be able to be Gold VIP. But you still have to work within the points framework of the VIP program AS IT CURRENTLY EXISTS...
If you just want a week of timeshare somewhere, I wouldn't even suggest this, as it's not going to matter, just buy a resell contract at the lowest maintenance fee schedule and be done with it. VIP benefits won't matter to you...
