Hello Dale,
I'm also a "big boy" at 105 kg.
I know the problem with the thighs. What you definitely have to pay attention to when expanding your thighs is that the proportions still have to be right.
You can do a lot with the coverstrips, but even that has its limits. You may need to add pieces to the legs to maintain the shape. If that doesn't work - Ross from RWA offers parts for us "big boys".
My armor is from Troopermaster. I used wider cover strips at the front and back (2 cm) and didn't completely join the two leg parts behind the stripes.
To answer your question: There will be a problem with your thighs for Lebel 2. The proportions are no longer correct. The stripes are too wide and the thighs are too wide in the lower area. The stripes also go down too far on the left thigh, so you just have to reconstruct the missing part. Everything should seem harmonious.
Here are pictures of my thighs (although my thighs are "relatively" normal - for me the problem is my stomach.)
I also had to "reconstruct" parts of the thigh because there was too big a gap in the knee area. Here are pictures of my thighs from the front and back.
And here are the areas in your case that could lead to problems at level 2:
