That's essentially what the Gunboat does.I think too many TIE variants really dilutes the theme of the Imperial forces
TIEs ARE the theme of Imperial starfighter forces. Adding a bunch of ships that aren't TIEs are what causes dilution of that theme.
But the Lambda Shuttle is also inherently imperial, as is the Star Destroyer, and the Death Star, and the stormtroopers, and the AT-AT walkers, etc. And none of them look at all like a TIE. You need to expand the design space, or soon it becomes overused. Can you say with a straight face that the TIE style has not been overused?
Would you have really preferred that the Battle of Hoth had been fought against these things?
I mean, once you start perverting the geniality of the original design, it becomes silly. Would you prefer all of these designs rather than anything that isn't a TIE?
Some of them are just hilarious. Some of them could be called TIE Pokemon, TIE Ewok Glider, or TIE Dildo. Look at the TIE Raptor!
The TIE Lone Scout looks like a TIE Travelling Pet Box. And the TIE Starcruiser is just sad.
One thing I hate with the E-Wing and the Z95 is precisely how similar they are to the X-Wing. I understand the Z95 was a Ralph McQuarrie early concept of the X-Wing, and so the EU writers reused it when they had to come with an earlier model of a rebel starfighter. But the E-Wing is just lazy. It's the X-Wing with two wings off.
"Rebel starfighter" must mean something else than "cosmetic variation of the starfighters we already know".
The design of the A-Wing or the B-Wing were nothing at all like the X-Wing or Y-Wing. They brought fresh new ideas when ROTJ came out.
In the same way, Imperial starfighter doesn't have to mean "TIE variant" when it is well established that the Empire used several manufacturers.
