Yeah, another one of these. Did it about a week back and forgot about it until now. If it looks like an upside-down modification of the Walker, there's a reason for that. The actual show did pretty much the same thing with the design that they used. Although it wasn't really intentional on my part, my take on the design actually might be able to convincingly pass as a TOS-era refit of the NX-Class from ENT.
