I don't think that would fit on the front.

I'm running a 20x8.5 et57 with a 7mm spacer so that's effectively et50 and the wheel is almost flush. Some people run 10/12mm spacers so that would be 47mm or 45mm effective offsett.

A 20x9 et40 would give you 4mm more clearance inside but extend 16mm mm further than my setup and I think that may poke excessively.

Apex has a good fitment guide and their most agressive setups are running 9 inch wide wheels with an et46 up front.

I found this online offset calculator about a year ago. Could give it a try.

I was going to link to the same thing. The apex guide is a great reference.
