speaking for myself only, i'm not sure that i would make the tcp_ip_abort_interval only 60 seconds (60000 milliseconds).

if the TCP retransmission rate is 20%, the network round-trip delays would have to be really nasty and variable for there to be 20% spurrious TCP retransmissions. i'd take packet traces first to try and confirm that the retransmission timeouts were indeed caused by too short a value. if they were not, increasing the tcp_rexmit_interval_initial may only make things slower.

also, if the retransmissions are spurrious and caused by too low a timer, the stat to see would be the tcp retransmission _timeouts_ not simply the data packets retransmitted - it is possible to get a data packet retransmitted without a timeout.

setting tcp_smoothed_rtt_enable (I think that is the name) may be more useful than messing with the tcp_rexmit_interval_initial
