Is it possible that the Peapers did make a Prothean-Reaper? And the Protheans had been aware of the Reapers destroying the vangaurd, but the Reapers invaded from the Alpha Relay, but had little resorces, so they sent a small force to create a specimen, which would attack and unleash the other Reapers?

One problem with this is that the Keepers were still under the influence of the Reapers. Or were they? It says it's possible they were aware of the Reapers. So, could they have began "thwarting" the Reapers, but without knowledge of the Alpha Relay, were attacked by the the newly arrived reapers, who were unable to push on, but the Prothean Reaper could, being new and full of fuel or whatever.

And, while the other Reapers awaited, running low on resources, this thing brought them back, dieing in the progress.

The other problem is why not do what they are doing in Mass Effect 2? Like I said, they are low on resources, and can only risk sending the Reapers who have enough power left, as they would loose more numbers then they would sending a small number of reapers with more energy then any other.

Now, with the Prothean Reaper dead, and most colonies destroyed, there is not enough protheans to make another, and thus they leave, and the scientists from Illos contunue what they had started before.
