They already did that. They designed and built the He-274 and the He-277.

Notes:
Originally designated He 177 A-4, the He 274 was a high-altitude development of the He 177. Like the He 277, the He 274 dispensed with coupled engines and mounted four single powerplants. While originally considered a version of the He 177, growing incompatability of parts led to the redesignation to He 274 and reassignment of the project to SAUF. French resistance workers conspired to slow down development of the He 274 so that the prototypes were not ready at the time of the German withdrawal in July 1944. The French took possession of the prototypes and redesignated them ASA 01A. The prototypes finally flew in December 1945 with French markings.

Notes:
An attempt by Heinkel to rectify the problems of the He 177 by mounting four single engines in place of the dual coupled engines, the He 277 was originally met with indifference by Goering. Heinkel was actually banned from developing this aircraft and secretly proceeded by designating it the He 177B. During a meeting with Hitler, Heinkel mentioned the aircraft as a solution to a specification Hitler was making. Hitler ordered the type into production, at which point it reclaimed it's legitimate name of He 277. Numerous prototypes were built but on July 3, 1944 production was halted as the German aviation industry focused on fighter production..
