SOCOM established 1975 ?

Is there any way that the US military, instead of only forming SOCOM as a joint service command in 1987 after the hard experience of actual or near failure (EAGLE CLAW, URGENT FURY), could've done so immediately after the hard-won experience of Vietnam (poss after the MAYAGUEZ fiasco, or even maybe dating back to 1970 to capitalise on SOG & KING PIN experience) ? How would the US armed forces have looked with an earlier SOCOM ?
