Generally, all common electrical plugs and receptacles (straight-blade,
twist-lock, IEC, and CEE) are physically sized and keyed differently, so
that they can't be connected together, to keep people from connecting
loads that require a specific voltage/current to supplies that aren't
intended to provide it.
While it's not uncommon for someone to replace a plug with "the right
kind", this can (in order of badness):
1. start a fire
2. short out and (hopefully) trip a breaker - that's what breakers are for!
3. violate building/electrical codes
4. void your device's warranty
As others have mentioned, just "making it work", rather than making it
work correctly, can be bad news.
People often fancy themselves unlicensed/uncertified electricians. I've
seen some of the handiwork from such people, and while their creativity is
impressive, having to rip their stuff out and re-do it is not fun.
