Hacking Delay Tap Tempo Mode? Momentary switch auto connect/release?

[brand0nized]

Looking to hack a Behringer EM600's Tap Tempo mode. Stock, you have to hold the footswitch down for 2 seconds to enter tap tempo mode.

Here's what I'm after:
How can I make the momentary switch automatically connect for 2 seconds every time power is supplied to the pedal and then automatically release after the 2 seconds, leaving the pedal in tap tempo mode every time power is applied to the pedal? What sort of options do I have?

I am rehousing this delay with a mixer circuit, therefore the onboard momentary switch will no longer be needed for the bypass function, as the delay will always be on running at 100% wet.
