Are there any risks to merge vertexes on patches in one? Like, taking the corners of a square patch and make a triangle?

Patches don't seal so even if you create a leak somehow, it would've leaked anyway. The only issue is shadows. If the patch casts shadows the leak would make shadow silhouette calculations more complex.

The only downside, minor, I've seen is that the polygon normals get a little glitchy (darkened) towards the fusion point. In terms of texturing, you'd need to paste from a brush to avoid massive distortion.
