Dynamic timeline selection for embedded timelines - Hashtag Timeline

Question

I've followed the guide here to add multiple widgets using the same widget id and this works perfectly fine for User timeline.

Snippet ----

<a class="twitter-timeline" href="https://twitter.com/benward" data-widget-id="[id]" data-screen-name="benward"> <a class="twitter-timeline" href="https://twitter.com/endform" data-widget-id="[id]" data-screen-name="endform"> <a class="twitter-timeline" href="https://twitter.com/kang" data-widget-id="[id]" data-screen-name="kang"> <a class="twitter-timeline" href="https://twitter.com/brianellin" data-widget-id="[id]" data-screen-name="brianellin"> What i would want to do is do the same( show different widgets ) for multiple hashtags - #MH17 , #MH370 on the same page. But these tags change for each article on a page.

I want to know if either of these are possible.

Make the same guide available for search query to "https://twitter.com/search?q=%23MH17" and "https://twitter.com/search?q=%23MH370" without creating a widget manually from twitter page. Timeline changes when i change the "data-screen-name" property. Is there something like "data-hashtag-name" ?
Use twitter API or something to automate the process of creating widget from the browser using Auth Token - Secret ?
