Why not use 1NT-(p)-4♣ instead for something like "5-5 majors Texas", or possibly "diamonds and a major" Texas? "Texas Stayman"?
I use 4♣ for 5+/5+ majors; not sure I would call it "Texas". I would not be surprised if this were the most popular meaning ...after Gerber.
I also play Texas Transfers, which leaves 4♠ available as an ace-asking bid. Never comes up.
