what's your native language? there might be someone else here who could help you out a little better, because I think google translator is not being accurate in this case.
but it seems like you're asking if someone could make a TV style speedometer for the on screen display in game.
Technically I think that yes it would be possible.
The problem is that CM seem to have made their games hard to modify. So I'm not sure that someone here has the ability or time to do this.
Anyways, go to the F1 2011 mods forum and look for a Mod Request thread, that's where you should ask this question.
