It'll be "interesting".

You know, funny thing about suspension tuning...
IT IS A VOODOO science. Actually calling it science would be too kind. There are so many variables involved here that sometimes, what will make a specific set-up work won't work for another set-up.
And I don't claim to be any sort of expert on these matters. All I know is, a lot of times when I get advice from other racer or instructor friends when it comes to suspension (and that includes wheels and tires) they can sometimes seem counter-intuitive...But for some reason, counter-intuitive or not, they work.
THERE REALLY IS NO RULE OF THUMB. Despite the fact that none of my racer and instructor friends use anything more than 5mm off from OEM offset (or the equivalent based on width of wheel), it doesn't mean that so-called "aggressive offset" won't work for someone else with a different set of compromises on their suspension.
And I've seen Frankenstein suspension systems work and work well. Granted they were put together by someone who knows a lot more than what I know, but it CAN work. There are some basic guidelines you can follow, but at the end of the day...
The only way for you to know for sure if a certain setup works or not, is by TESTING. Go do as many laps as you can, eliminate the variables, and systematically test your adjustments to find out what works and does not work for you. That is the ONLY thing any of you should take away from anything I say on this topic.
