He could easily use a power darlington and a TL431 instead of an existing linreg, giving him a dozen amps of room if he really wants to. TL431s are real good to have around.
I'd suggest a MOSFET instead, but he'd need one designed for linear action. I've heard about microscopic thermal runaway in normal switching MOSFETs run in the linear region.
