I did, I have made all the variants of the PSLV using 6 Thumper SRBs for the first stage, a mainsail engine with a orange rockomax tank for the second stage, a Skipper engine with the rockomax X-200-32 fuel tank for the third stage and a Poodle with the X200-8 for the last stage followed by a 2.5m fairing shaped similar to the heat shield of the actual PSLV.
The PSLV-XL uses 8 SRBs instead of 6 and has an extra fuel tank in every stage.
The PSLV-C uses four boosters with some fuel removed from each stage.
The PSLV has served me well and works better than the Kerbal X while costing only 47k for the normal variant, 40k for the CA variant and 50k for the XL variant.
I have made a GSLV Mk-III with the first stage as two boosters of mainsail engines along with an orange rockomax booster and a X-200-17 tank. The second stage is a twin boar engine while the third is a skipper with 3 X-200-16 fuel tanks. It costs only 72k and can lift mun and minmus landers as well as probes to most of the planets.
