Is it possible to do without intermediate iron?

Question

Mikrotik

Good day! Such a situation from dip comes a range of addresses like 89.89.89.240/28. But you can go to the Internet with these addresses through another network 95.95.95.90/30. Now the tick is given a network / 28 after there is a piece of iron with a network of 30, is it possible to somehow get rid of excess iron, or is there no point in this?

I suppose, let's put a /30 network on port 10 on the first /28 and the gateway for /28 will be port 10
