The pegs on the GSA are made of stainless steel that's perfectly weldable.
Cut them insert a bit of stainless flat bar and weld them back up.
TIG or stainless rods, dead easy and cheap.
It works, I lowered mine and made them pivotable as well.
Mine a re lowered about 35 mm or so.
A big difference in knee angle.
I wish I had bought a GSA a long time ago
and now I drink Orange Crush as well, double up now, a 990Adv and a 950 SER
