if you are 100 percent sure that you will never need it and won't sell the bike, then do it - it is after all excess weight. I removed v-brake bosses from a rockshox SID fork for that reason.
I used a hacksaw, an angle grinder - be careful as one slip and cause much damge - and then finished off with a dremel sanding disc.
personally I think you are making a mistake and should be fittinng discs but hey, your choice to stick with archaic vees.
