[PF] Multiple uses of Metapsionic feats?

[jaybird]

Each Metapsionic feat requires you to expend focus. Essentially, what this seems to mean is that you are only able to apply one Metapsionic feat to any power at a time. Is there a way to overcome that limitation, possibly with some Psicrystal shenanigans?

The Psicrystal Containment feat allows your Psicrystal to hold and expend a separate Psionic Focus, thus giving you two to spend on Metapsionic feats. There's also a feat called Metapsionic Mastery, which lets you use metapsionic feats without expending your focus, at the cost of 2 power points per feat used; However, this only works on one specific power of your choice.

Edit: The Psicrystal Imprinter prestige class can be used to effectively Empower, Extend or Twin a power without expending focus or increasing manifestation cost; Doing so increases the manifesting time to a full-round action (or adds an additional full-round action if the power already took that that long).

Edit 2: There are also metapsionic feats which require you to maintain your focus, rather than expend it. Offhand the only one I can think of is Merciful Power, but there might be others.
