If I put a shot glass of rum or tequila in my humidor, will the cigars absorb the flavor?

I bought of couple of JM Dominicans and sundry other cheap robustos. My hydration unit is a piece of s***,so I already keep three shot glasses of water i there, which keeps the humidity at 70-80%. Should I replace one or two with the liquor? Is there another liquor I should use? It’s just that rum is my favorite, and tequila sounds like a good taste for a cigar.
