metal bases were put in for a reason, which for now escapes me.
You mention metal base 6sn7, but there have been metal base 5ar4, EL34. Sovtek even made a 6550 with a phenolic base.
i believe it has something to do with capacitances among the pins and their leads.
if you are worried make sure the teflon is wound between the base and lower mica sheet. Most heat is generated from the plates which lie between the top n bottom sheets. Keep the glass area between the mica sheets clear to maintain heat dissipation
You can also use PEARL coolers, but they tend to roll off the top end a bit.
