The program MSPCrunch may do what you want. However, if the blast searching
is also batched, you can specify the e-value cutoffs in the blast client,
blastcl3 or blastall. In the scenario that you want to update the e-value
for the updated search, well, this value should be accurate given the search
space and lengths of the sequences; the computed e-value doesn't need to be
"fixed".
