QQQ gets the leverage from, among other things, swap agreements and futures. I don’t think what you have could be reasonably considered “pseudo-QQQ”. It’s like copying a cake recipe, but leaving out the flour and eggs because they are too expensive.
Even given that, I don't see any reason I couldn't also just mimic what QQQ does with the MCP.
