Well, trying too many things might not help: When we send hybridoma cells
to other labs, we prefer to send them coming from a growing culture at RT
as frequently cells dont make the change from IMDM to RPMI immediately.
(out of topic: then the recieving lab just adds their medium gradually
over a period of time). The other way from RPMI to IMDM I had problems
once, so rather do not change the medium and keep the one that cells were
growing in before freezing.
In some posting IL-6 was mentioned, and this helped a lot to increase
viability in my hands.

good luck
