It would be bad manners, period. The problem is not that you are short on cash but that your guest list is too long. Besides, showers need to be small enough for guests to get to know each other. I suggest that, instead of thinking of your shower as one big meet-and-greet, you try and consider it a cozy, intimate gathering of your nearest and dearest.
As soon you get over the crazy idea of charging people admission, cut your list way down and sketch out a reasonable budget. Or consider asking those friends who made the original suggestion to host your little party themselves.
