Should be fine, the RX300 Mk2 wheels I have (which I am now selling with excellent winter tyres fitted ) were bought from a lady who had them fitted to her RAV4, so I guess anywhichway will work.
The RAV wheels would be 10mm closer to the suspension/inner arches than the standard wheels. might be worth taking a squint to see if there is clearance there, should be fine as most clearances are designed with snow chain clearance, and thats slightly more than 10-15mm
