To replace or not to replace...

Okay, I have a few filters that I made when I started out using Filter Forge which are ... suboptimal And I have been trying to find ways to replace these filters through "updating" them, but pretty much I just replace them with better filters. So my question is this, would anyone mind if I replaced
http://www.filterforge.com/filters/2764.html
with a brand new filter, that still gets a techno-computer-esque effect? I know that with the bad track record of the old filter, the new filter doesn't stand as good a chance of getting HU; however, I hate looking at my library and being happy with 95 % of my filters, and cringing when I see some of the uglier... I mean suboptimal ones.

Thoughts, suggestions? Is there a way to request FF to just delete some of the filters I hate? That would be even better because then I could just publish the new filters on a clean slate.
