Hi Ajay,
I think 1/48 aircraft would look way out of scale next to 1/35 armour. Even 1/35 next to 1/32 is noticeable. For reference here is a shot of two figures I'm working on. 1/35 on the left, and 54mm (1/32) on the right. Quite close in scale but still very different.
If you're set one matching scale there's an extensive 1/48 armour series from Tamiya, to go along all those 1/48 aircraft you've found, so you could switch and maintain a constant scale.
The easiest way is to just build what you're interested in at the time, and hang the scale difference.
