Today, I decided to just swap Baylan's legs with Reva's like others have done. I'm surprised what a big difference it makes. Here's some comparisons.
Before the swap compared to Shin.
After the swap
Before compared to other Inquisitors (he's shorter than the Grand Inquisitor)
After the swap, he's at least as tall as him.
He's even taller than Marrok now.
And here's how Reva looks with Baylan's legs. She's much shorter now. Have to decide what I'll do with her later.
