Those I'm nearly sure I could get, if I can pool caches amongst ISPs. The current constraints are issues to any content provider, not just for local ISPs.
two issues here: the smaller issue is that CDNs sometimes want their own routable IP address blocks, especially if they're connecting directly to the IXP, which usually means /24 in practice. It doesn't always happen, and sometimes the CDN is happy to use provider address space (i.e. IXP), or smaller address blocks. But it's something to note.
The bigger issue is: who pays the transit costs for the CDN's cache-fill requirements? CDNs typically won't pay for cache-fill for installations like this, and if one local ISP is pulling disproportionate quantities of data compared to other ISPs at the IXP, then this can cause problems unless there's an shared billing mechanism built in.
