Solr Autosuggest & Spell check - search

Question

I am using solr 3.6. (sorry to say!) and having a hard time implementing autosuggest and spellcheck simultaneously. I am using Suggester for autosuggest and do not want to use IndexBasedSpellChecker for spell checking. Is it possible to configure autosuggest and spellcheck in a single request handler ??
For example: if I search for 'blan', solr suggests 'blanket' and retrieve search results. However if I type 'blantet' or 'blanpet', I get 0 results and no suggestions or spelling corrections. I just need spell correction from 'blantet' to 'blanket' so that I can show 'Did you mean ?' on my page.
Using standard parser.
Thanks in advance.

Not sure about version 3.6, but following configurations working for me on higher version 6.
