The f-stop reduction effect applies for teleconverters that are inserted between the lens and the camera body type. Front-mount teleconverters don't necessarily reduce the f-stop, because there is flexibility in the len design (size, mainly) to compensate for the reduction in light captured when you reduce the angle of view.
From what I know, TC-E2 and TC-E3 are designed with the diameter that maintains the same in-camera f-stop setting. i.e., when you use either of these tele-converters, there is no f-stop reduction.
When I made my own scope for my CP995, the scope actually increased the effective apperture, such that the camera (in aperture priority mode) metered a higher shutter speed with the scope attached.

Wow! You essentially have a light amplifier! You DIY-ed a telescope?
