Tiger, Iron Duke, and treaty-retention politics

Was there any thought to retaining HMS Tiger instead of HMS Iron Duke under treaty reductions, with a later refit?

Yes, but Iron Duke's role as the First World War fleet flagship and its political-symbolic value made it the status ship to retain.

Retaining Tiger was considered, but Iron Duke carried the political weight of having been the First World War fleet flagship. That history made it the status ship politicians wanted to keep. Its association with a former prime minister reinforced the case for preservation. The proposed later armament refit for Tiger is left unassessed.
