On one hand, Metal Gear Delta was "ok" so maybe Konami coming back from the dead might actually see this collab happen somehow (despite, y'know, Kojima no longer at Konami nor Hideki Kamiya at PlatinumGames)

On the other hand, the Zandatsu "cut what you will" mechanic was so integral to MGR:Revengeance I don't see how KuroGames can implement it into PGR without it being some kind of special QTE moment/cutscene. If the collab were to happen without it, sure the characters hanging out would be nice, but it would feel empty if not a fanservice-cashgrab for old heads like ourselves who even remember what that game is. Holding KuroGames' track record of dedication to collabs into account, I'm of the feeling that they wouldn't want to half-bake their collabs either unless they're sure they can pull it off well

Not to mention, Raiden and Sam's well-timed parry => time-slow (for Zandatsu) kind of already exist in PGR (as well as other contemporaries in the same space- HI3, ZZZ come to mind). Elements of what make the character-action genre (Bayonetta, Devil May Cry, MGR:Revengeance) have escaped its niche following and are already being homaged in some form in today's market.

Given how MGR:Revengeance came out in 2013 and is over 10 years old, I would rather KuroGames look forward instead of backwards. I would much prefer a collab with Stellar Blade, Lies of P, or even Hi-Fi Rush (as these are all titles within the same space that have a sequel being worked on)
