Finnish 4wd rally cars, the future?

I know that I'm touching a sensitive subject here, but the idea is so tempting that I just can't let it pass. Could we use non-homologated cars in Finnish 4wd championship? The same goes for 2wd cars also, but in my eyes the 4wd class is more vulnerable with the already high costs and cars that are sooner or later going to meet the end of their homologation.

I read from new Hanaa! -magazine about Esapekka Lappi's rally in Spain and there it was mentioned that in Spain there is a possibility to build your own "N1" 4wd rally cars using Mitsusubishi Evo's or Subaru's mechanical parts. The suspension can be whatever and same goes for electrics. Weight of the car either 1200kg or 1300kg depending if you are using a 34mm or 36mm restrictor. Chassis has to be from a production car (I'm not interested in seeing "I did it myself group B fiberglass works of art") and you can fit a bodykit to fit the axles.

As an eternal pessimist I'm worried that the price for new R5 cars is going to be out of reach for many 4wd drivers in Finland. And I guess that goes for many other countries also. The possibility to lift the group N mechanical parts to some other car would enable having many different brands on our rally stages which otherwise would never show up to Finnish rallying. All you need is a cheap chassis donor car from Germany or one that some Finnish insurance company has "bought" with exploded air bags. Then put the roll cage in and fit the mechanical parts. I'm not even trying to speculate if the mechanics fit to some car or would the suspension work at all, but I can't help but speculate with some of the cars out there. Or what how big would the resale market for these cars be. For example your own WRC/S2000 replicas: Fabia, Fiesta, DS3, Countryman or Polo
Why stop there if you can use your imagination? Here are some of my personal favorites for thinking outside the box: Alfa Romeo Giulietta, BMW 135 Coupe, Hyundai Veloster, Toyota GT86 and Audi A1.

One can always speculate with wild ideas. Most likely these kind of rule changes are never going to happen in Finland, but it's always fun to think "what if".
