I've not modded any of my tents but if I was I would make sure that any stitching was appropriate to it's function e.g. a new anchor point for guy lines would be made as close to or beyond the spec of those on the tent already but a new pocket would need a lot less.
finally any stitching would need plenty of seam sealer to ensure that you don't compromise the water proofing of the tent
