I don't think so. I don't exactly know what you mean by "the poor mans Sveshnikov", but I'm guessing you're asking me if I think it's a worse version of the Sveshnikov.
To answer....no. I don't think so at all. I think it's very different. At least in my preferred lines, or in the lines I think are best, it doesn't resemble a Sveshnikov enough to draw a lot of parallels. For example, after
6. c4 Be7 7. N1c3 a6 8. Na3 f5 9. exf5 Bxf5 10. Bd3 Be6 11. 0-0 Nf6 12. Nc2, the structure doesn't really resemble a Sveshnkov all that much. Yes, Black has pushed ...f5, but he doesn't have doubled f-pawns, and his pawn hasn't hit the b5 square yet. It's completely different.
One thing I came across was a couple of players who religiously play the Kalashnikov and who have ridiculously outlandish scores with it. For instance, Alexander Moiseenko has, as Black, scored +32 =19 -9 after 4...e5, and after 5. Nb5 d6 6. N1c3 a6 7. Na3 Be7, scored +8 =5 -0 !
Another exponent of the Kalashnikov, Vyacheslav Ikonnikov, has a score of +41 =29 -12, and after the same line (7...Be7!?) +7 =9 -3, when two of his loses were to 2600+ players.
Another nice thing is that the Kalashnikov receives incredibly shabby coverage in most tomes. The newest MCO doesn't even give this 7...Be7 line, and Pinski's coverage, if I remember, either neglects a certain better Black move or stops earlier. Khalifman's coverage is the best, giving
7...Be7!? 8. Nc4! b5 9. Ne3 Nf6 10. g3 0-0 11. Bg2 b4 12. Nd5 Nxd5 13. Nxd5 Bg5 14. Bxg5 Qxg5 15. a3!? += That said, I think after 15...bxa3! 16. Rxa3 Rb8! Black is equal for sure.
