There are some themes that have the "LCR" feauture. It's the easiest way to make modifications like the one you want. Most themes that have used the morphogenesis theme.html code might have this.
The order is set at the top of the head of the theme.html in these lines:
<{* Center blocks display order valid values are: lrc (left right / center) lcr (left center right) clr (center / left right) *}>
<{assign var=theme_top_order value=clr}>
<{assign var=theme_bottom_order value=clr}>
but it can't be just inserted into any theme, the html would need to follow some of the parameters morphogenesis has. If your theme has this, it would be changing the "lrc" top value to "clr".
Otherwise the only way is editing the theme.html and carefully modifying the blocks default positioning.
