Seasonal DLCs?

Just an idea as a suggestion for a DLC.

Perhaps it'd be nice if you could consider making sort of "seasonal" DLCs?

I'll take 1991 season as an example here:
In addition to whatever there's already in game, you put up in a 1991 DLC a few stages that could represent the rallies not in the original game (Argentina, San Remo,  RAC...), a few car models of main contenders from the season (Ford Sierra, Toyota Celica, Mazda 323...) and a few liveries (works, preferably, or FINA Jolly Club for Lancia...) for the cars already in game?

In this way, many different seasons could be made playable, each as a separate DLC, of course.
I can say I myself would love to be able to drive some cars against its contemporary rivals and trying to re-create some past WRC seasons!
