Mixing bricks and blocks

Hi all. I'm building a single story extension with a warm flat roof and parepet walls under permitted development. In order for me to have the same height ceiling as my living room I'll need to raise the inside blockwork up by roughly 65mm to sit the ceiling joists on, is it possible to use a single course of engineering bricks on Top of the block work so the joists can sit on that, bare in mind there will be 3 more courses of block's to lay on Top of the engineering bricks. I'm using brick on the outside skin and solid block on the inside with a 100mm cavity. I know I can use concrete commons but I'm struggling to find somewhere local that stocks them. Thanks
