Lexus pickup

i thought what if Lexus made a pickup? Lexus already has 3 versions of Toyotas SUV's. So why not expand their line and have a pickup truck? They would just make a version of Toyota's Tundra. It would compete with the Cadillac Escalade EXT and (if FOrd puts it into production) the Lincoln Mark LT (a Lincoln version of the current Ford F-150). Is this a good idea? I think it is, but i want to know if anybody else thinks so.
