As I feared, when looping other residue to change res.id.position, my script fails as position can not be modified. How could I do this? Should I delete position and re-create it?

Though you can't modify res.id.position, you can overwrite res.id entirely.  So something like:

from chimera import MolResId
for r in residues:
	r.id = MolResId(r.id.chainId, r.id.position+230, r.id.insertionCode)
