TCP spoofing

I am doing research on Web Proxy server in satellite channel.
In order to avoid bandwidth-delay problem in long round trip channel,
I am trying to minimize number of packets BTW client and Proxy.
I made TCP spoofing scheme between TCP and IP, making Client feel like
TCP conection.
After Proxy receiving all data from IP server, it send data down to client
in big chuck of data(large MSS).  Although Client send ACK to Proxy at TCP
layer, spoofing layer absorbs ACK so that nothing is sent to PROXY.

What is the problem that may occur in this case?
Your comment really help my research.
