I think that is it logically inconsistent to be happy with the work of the foundation, but reject their fork. They have philosophically stated that the social contract of ethereum is mutable and they are free to change it at any time. There simply is too much risk in deploying infrastructure when this approach is being taken.
IOHK will suggest a new roadmap with the support and guidance of the ETC community, conduct research to accommodate it and implement full clients and whatever other infrastructure is required to run these changes. I fully admit and understand that some subset of the ETC community will not accept any roadmap we proposal for whatever personal reason. So we'll do our best to try to curate a process that reflects the will of the bulk of the community given respect to the core principles that brought us all here in the first place such as immutability.
