Since you're unlikely to be sharing memory with your background processor, what you'd really be doing is marshaling the object on enqueue and unmarshaling on decode. In that case, you're no more susceptible to further modifications to the data than you would be with a DB lookup.

There of course may be other issues with marshaling. E.g., marshaling of procs is particularly tricky. But I've been marshaling with sidekiq for the past couple months and really haven't run into any problems. And it cleaned up the code a fair bit because I basically treat it as an RPC without any of the ceremonious DB lookups at the start of every async method.
