In order to do that you would need to route it to a specific IP address in the first block, and your customer would have to have a router at that IP address which then connects to the second block. Same with assigning a /30; if your switch's IP is .1 and you're routing the customer's blocks to .2, the device at the .2 address would need to route at layer 3 between tthree networks.
If the customer doesn't have a layer 3 device, then assigning the second /29 as a secondary IP is really your only option, but you may also want to consider migrating the customer to a larger block, say a /28 or /27, and reclaiming the /29. This can be done pretty seamlessly with secondary IPs on your switch and his servers; just configure the new block alongside the old and have the customer change his DNS records when the new block is set up.
