Some TARDISes don't have recipes, and some don't deserve items/recipes. This thread is suggesting possible recipes and removal of items.

 

Toyota, Copper, Coral and Vanilla:

The Toyota, Coral and Copper all use the same sort of recipe as the current police box TARDISes, with beacons (as these are more high-scale interiors), and different items in each centre. Instead of a beacon, it could be a diamond block, or have glowstone with solid block centres. The Vanilla TARDIS recipe is crafted similarly to how it is built, with the redstone lamp and stone slabs on the top, an iron door, and lapis walls.

Hexon and Floral (+ Capaldi Sonic)
The Hexon is an iron main, with a diamond on top and dyes in the center mimicking the strange roundels on the exterior. There are probably better alternatives to the dyes, but I couldn't think of any. The diamond might be better as a block. The Floral mimics both the interior and exterior with the leaves, logs and vines. The diamond may work better as a block. 
The Capaldi Sonic is the same as all the other sonics currently, but with Zeiton-7 for the top.

 

Removal of current TARDIS Exteriors from item form, making them only in the Chameleon Circuit:

This would lower the count of Default interiors, and also remove double-up models of exteriors in the creative tab. 
Possible exteriors to remove:

If the TARDIS had a custom interior, it could stay in the inventory/gain a recipe, but exteriors like A, B, C, Default, Bad Wolf and Clara Tribute should only have one in the inventory in total, and the rest as chameleon circuits. This would allow for more inventory room for TARDISes, and also make more people actually use the Chameleon Circuit.

 

Favourite Exteriors:

This would allow you to save exteriors that you like to use to a list, so you don't have to scroll through exteriors you dislike/don't want to look at. So, if you only used the Alpha, Beta, Delta, Gamma and TT exteriors, they could be added to the list via a "favourites" button.

 

If you have ideas on how to change the recipes to be more fair, or more exteriors that should become Chameleon Circuit only (or shouldn't be Chameleon Circuit) only, comment them down below.

I have no idea. I'm just here.

i know obtaining tardises is supposed to be alot more difficult,  but i think a nether star is a  bit too much

 

in my opinion,  i agree with what you said in the hexon and floral tardises,  that the diamonds would be better off as diamond blocks, and i mean that it would apply to all tardises, and some might even use emerald blocks for that much more challenge

 "emerald blocks for that much more challenge" I've been able to get lots of emeralds before even getting iron via villager trading. But the rest of this is quite good.

well,   maybe condensed diamond  blocks?   this could be an addition for crafting only,  it would work as an item,  not a block,    

 

either a 1x2     or a 2x2 shape of diamond blocks would be put in a crafting table to get one condensed diamond block,  which would be used in place of the diamond in current tardis recipes
