My Solo MMR is at almost 4k and I'm pretty confident I could reliably stomp 2.4k pubs. I think your smurf MMR will drop to your actual level soon.
Also, I think MMR is a shockingly accurate metric.
At 4k MMR, you sometimes play against smurfs of people at 3k MMR (and lose). So, I am not sure you could reliably stomp a team of 2.4k pubs against you and four other 2.4k pubs.
Moreover, it is a team game afterall, and carrying a team of 2.4k pubs is hard. Everyone stops farming at 15 min and tries to fight mid, so if you lose one teamfight there, there is usually no possible comeback, since it will be endless lost teamfights mid.
