Though poking holes in your ingress route filters isn't a good thing, you 
really don't have any other options (when considering connectivity to the 
destinations of the direct link to the customer becomes unavailable).

You should also note that depending on what range (first octet) the address 
space is allocated from, the longer prefixes may be filtered by some 
providers, which may cause problems if your link to the customer becomes 
unavailable.

And don't forget, one /22 is still much better than four /24s :-)
