Portemanteau band names?
 

So I need to come up with a cool band name. I like portemanteau names and have come up with these so far :

Sylanide (Silence and Cyanide)
Blixen (Bliss and Vixen)
Gasolinear (Gasoline and Linear)
Sparkosis (Spark and Arkosic)
Funconditional (Fun and unconditional)
Essempathy (Essence and empathy)
Paradoxyde (Paradox and oxyde)

Could you please tell me which ones of these are good or bad? And it would be AMAZING if you could suggest some new names. Thanks!
(By the way, the band has no particular genre. It likes variety.)

Sylanide - Sucks.
Blixen - Sucks. Sounds too much like one of Santa's reindeer.
Gasolinear - Sucks. Trying way too hard.
Sparkosis - Not too bad. Probably the best of the bunch.
Funconditional - Okay if you're target audience is 7 year olds. It has also been used numerous times as an album name by various artists.
Essempathy - Sucks.
Paradoxyde - Sucks. Attaching oxygen molecules to words doesn't make them cool.


As far as picking out a portmanteau for a band name, I would gather all of the band members together. Make a list of your musical influences, your goals as a band, words describing your musical style, your interests, etc. Just start putting words together and get a few that you like. Do an extensive internet search to make sure the word is not widely in use, trademarked or copyrighted.

Except for Funconditional, all of them are quite honestly awful. But I agree with Oojay, do what he suggested.
