Can I pay with something else in act 3?

I didn't expect that particular exchange with Big C would end up in me looking older..

I like committing to these big sacrifices in Role-playing games cuz it gives me hype, but the fact that I'm physically old feels abrupt and kinda ruins my role-playing fun.

Is there a way to gladly bare the burden, yet paying in some other kinds of currency?

Like, I wouldn't mind giving out my arm, a leg, an organ, or an eye? That would be cool for role plays. Hell, the gohstie guy even mentions 'Scarlet Blood'. I can happilly donate my blood.

Do they take kidneys?
