I’ve done a 500x5 fork mod on a RV7A, the increased nose height made it sit tail low like a stock 6A. If you did it to a 6A without using the longer 7A (or 9A) main gear legs, the plane would have even more of a tail low stance.
The effects to the 7 were lighter weight in the nose during taxi, special care in flare to avoid touching the nose before mains, and limit baggage carrying capacity somewhat because of the aft weight shift during taxi. These symptoms would definitely be even more pronounced if attempted on an otherwise stock 6A.
I also fab’d up a fork for a 8A and the owner ended up getting a unique nose gear leg fabricated to use for the installation to minimize the additional height &aft wheel positioning and other above mentioned undesirable byproducts.
Personally I would not recommend this mod & would rather suggest concentrating on the piloting skills to prevent these potential nose wheel related issues.
Maintain lots, upgraded - repaired - & modified more, rebuild a few, & built some too.
