They have worked together many, many times in the past. In fact, at one point DC asked Marvel to start making their books for them.

The thing is, when those things happened they were small fairly independent companies with the freedom to do whatever they wanted. The crossover events and amalgam and such were both good creative outlets and also hot sellers.

However, now DC is owned by Warner Brothers and Marvel is owned by Disney and those are two massive, massive companies for whom any benefit of cooperation is too small to make it worth it.
