How to perform a custom action before RemoveExistingProducts with After = "InstallValidate" on WiX

Question

I have something like this:

<InstallExecuteSequence>
  <RemoveExistingProducts After="InstallValidate"/>
</InstallExecuteSequence>

Since one of the unsuccessful attempts to uninstall, I need to perform a custom action to solve the problem before uninstalling ExistingProducts. Something in the lines:

<CustomAction Id="FixStuff" .. />

<InstallExecuteSequence>
  <Custom Action="FixStuff" Before="RemoveExistingProducts" />
  <RemoveExistingProducts After="InstallValidate"/>
</InstallExecuteSequence>

This, of course, does not work, since Custom Action cannot be prior to InstallInitialize. I would really like to remove existing products between InstallValidate and InstallInitialize, but I want to run FixStuff before uninstalling existing products.

Is it possible to do this?
