This battle is as interesting as imagining the Aussie batsmen of 1990's vs Marshall, Holding, Garner and Roberts.
What if the batting line up comprising of Greenidge, Haynes, Viv, Gomes, Lloyd and Dujon face massive turners like Murali, Warne and Saqlain on a turning pitch? Who wins?
Not sure there is a definitive answer, but here is a match might amuse some and steer as close to a definitive answer as you can ever get in a hypothetical question

That was as strong a West Indies line-up as was about at the time, same (batting) line-up that destroyed England 4-0 in 1988 - Greenidge, Haynes, Richardson, Hooper, Richards, Logie, Dujon, Harper, Marshall, Ambrose, Walsh.
But seriously you can simply look at the results of series in India and Pakistan.
West Indies (1980s)
83/84 West Indies won in India 3-0
87/88 West Indies drew in India 1-1
80/81 West Indies won in Pakistan 1-0
86/87 West Indies drew in Pakistan 1-1
Interestingly West Indies have only toured Pakistan eight times. Doesn't prove the West Indies could play a top spinner with a stick of rhubarb on a spinning wicket, but it does show their 80s side didn't have a lot of trouble playing spin with only two defeats in the 80s in India and Pakistan combined.
India's only win was the Test where Narendra Hirwani took eight in each innings to end with 16/136 in the Test.
Wasim Akram took six wickets in the 1st innings, Abdul Qadir took six in the 2nd with Imran taking the other four in the 2nd when Pakistan beat West Indies so pace did a lot of the damage.
