Welcome to the MW...
As Phyrox said, unfortunately, we dont get to choose kits like that. We cant say we want so and so and voila, someone comes in and builds it for us. Theres usually an interest check by the model builder themselves and if theres interested, then its built.
Also as Grayson72 said, most of those are Southern Cross and Mospeada units. A model builder here has gotten in trouble before making a "Robotech" unit. So I'll doubt seeing any of those being made anytime soon. As for your Macross requests:
1. 1/72 VEFR-1 Electronic Warfare Valkyrie - 1/60 or 1-72 resin upgrade for the yamato variable or hasigawa kit.
2. Destroid Defender,Destroid Tomahawk, Destroid Spartan, Destroid Phalanx
1/72, more detail, options and in resin.
Variable kits are very hard and difficult to design. It'll be very costly and it would need a lot of interest for it to be made. Being that the VEFR-1 isnt one of the main valks, interest might be scarce.
I would love to see better destroids myself... hopefully a modeler will be willing to take that job one day.
There was already another thread about this.
