Would a trade with Dwight Howard going to the Spurs be scary?

I just thought about this..I know Duncan has loss some explosiveness..and David Robinson was loss a little when Duncan came..but with Duncan by his side..he got a ring before he left...IDK how the cap would work..but i think if San Antonio got Dwight Howard to play center..let Duncan play PF..that would be the BEST frontcourt in the NBA!..no one would score over them..they could move Tony Parker for him..Matt Bonner and a pick. George Hill does just as much as Parker..so he will do fine at point..do u think this would be a good trade or no?
