IMO, the name is no problem.
Your knowhow to get in contact of a publisher and to convince him to take a look at your demo - that's the first step.
The second step is to convince him that you have a good and reliable team that delivers the required quality in time.
If you managed that, the engine doesn't matter at all - as long as its for PC only.
