Sounds the same as the SVO/Tbirds.  It's always hard to talk about
this stuff, because it's hard to visualize what the other person is

Effective, but unnecessary, plus you're losing metered air under
boost, and possibly sucking a little unmetered (and unfiltered!)
air back in during normal conditions.

Also effective, but unnecessary, because you're replacing what already
exists.  The hose through the solenoid is already a bypass, you don't
need another one.  All you need to do is control the flow through the
bypass rather than letting the computer do it, to set your own boost

Your way sounds as cheap as any, but it's simpler to control the
flow through the existing bleeder rather than adding another one.
I don't know which style system your Merkur uses, but the early
SVO style won't boost higher than stock unless you drill out the
solenoid side of the tee a little.  Then for all cases, you put
a valve in place of the solenoid and adjust it until peak boost
is where you want it.
