Can you change the crank and or S/C pulley in STU and take a weight penalty?

What car?

9.1.4.1.B.2: "Supercharged cars may be approved on a case-by-case basis..."

9.1.4.G.22: "...supercharged engines must use OEM crankshaft and supercharger pulleys."

Exceptions may exist within the Allowances/Requirements table; for example:

"Lotus Elise SC/ Lotus Exige SC ... Minimum 2.9” supercharger pulley..."

The 2004 Mini Cooper S in Super Touring U can run the JCW pulley but cannot change the crankshaft pulley. See Table A, STCS.
