Would megane 6th gear work in clio box?

I know some people feel a little uneasy about the clio box putting down 300bhp, personally I love the clio box. Motorways however become very tedious for anything over an hr or so.

Wonder would the meg 6th gear fit in the clio box so that the longer ration would make it a somewhat more pleasant drive for those longer journeys
 
No idea, i think it would, but it would be one hell of a jump from 5th to 6th.
 
I have zero issues with my Clio box, suits me perfectly. 6th is only used for cruising so it wouldn't bother me about the jump, would just make motorway driving more pleasant
