I like your thinking Girl ... Condensate lines acn be REALLY gross (see pic below). Here is what you can do:
1. Get a PVC elbow to fit your drain line where it reaches the drain cover.
2. Fit it to the line and with a Sharpie mark the diameter where it hits the drain cover. If it sits above the cover, you can get a short section of drain PVC to fit into it. Mark that diameter on the drain cover. Basic principle: You want the new cover hole to be tight so nothing can get into the drain .... or crawl out of it either. EWW
3. Drill holes and cut the drain cover to fit the new drain pipe extension. If you want to get really crazy, you could use some kitchen/bath silicone to seal it ... but that is probably not necessary.
4. Install the extension in the cover, slide it onto your drain pipe, screw down the cover.
Celebrate in a manner you enjoy!
