S!
Please find where I said the change to the wheels didn`t happen in the G4. In fact, find where I mentioned the G4 at all:

"The undercarriage on the F model 109 and G2 was essentially the same as the one on the 109E, and while it was sufficient for the weight increase of the F, the extra poundage of the DB605 in the G2 increased the stress on it to the point that collapses during landing were becoming very common, especially for aircraft which been in service for a few months. The Luftwaffe command staff asked for a redesign to fix the problem.
The Messerschmidt engineers found a way to replace the undercarriage. Unfortunately to do this, they had to create bumps in the wings to accomadate the larger and heavier struts and wheel components.
At the same time they replaced the undercarriage, they also replaced the 7.92mm Mg's with 13mm versions. This in turn nessesitated creating bumps in the engine cowling, and destroyed all the beautiful streamlining work which made the F model 109 the best looking mark of the breed.
All in all with the G6 they ended up with a considerably slower, heavier plane, with bigger guns, but generally inferior to the G2 in performance."

As I say: "...with the G6 they ENDED UP with a considerably slower, heavier plane..."
Get that: ENDED UP.
I never said there was no intervening models of 109G`s. My comparison was between the G2 and G6.
On the other hand, as noted above, you insisted the G6 DIDN`T have wheel changes or bumps in the wings for the wheels.
