:-) Volker, you forgot the TransparentProxy feature.
So the answer is yes, you can cascade the ftp-proxies using
it as a transparent ftp-proxy on the gateways. The problem is,
the ftp protocol doesn't support this, so you really need to
install it on the gateways, because you have to redirect all
outgoing requests to port 21 to the proxy.
If you and your ISP has a Linux Box as a router/gateway in
his net (of course, there may be other "non-Linux" gateways
between the two Linux gateways), it is possible to do this.
