<span style='color:red'>I thought of this, but I wasn't sure if this could work or not. I would like to do a character with this background, but I didn't know whether this goes against the rules, so I thought it best to ask.</span>
Nope, sorry. It's not possible for Aquabats to interbreed with other species, they've become to unique for that in their own evolution :)
<span style='color:red'>Okey. ^^ Thanks for telling me before I put it on a character and it ended up being rejected. :)</span>
Not a problem :) However, if their are certain traits from either of the species that you particularly fond of we might be able to find a way in incorporate them into your new character. Feel free to brainstorm in here.
<span style='color:red'>Thanks! X3 I think it'll take a lot of thought to create a character like that, but I try! XD</span>
