Who knows... if you really don't care about it give it a go...
For something less destructive, try Vaseline or beeswax or the like; something that can be removed later if desired. I'd suggest trying it out first to see hat kind of results you do get before making any mods.
Whatever you do, try to get a roll of film through it and processed to judge the results for your yourself before taking on an important shoot... better to be disappointed (or pleasantly surprised) if it's something you don't mind about so much rather than coming home from India only to find it's not what you wanted.
