The ~得る construction already implies possibility, so でき得る sounds redundant to me, like "if it's possible to be possible" (unless you were using できる to mean that something is finished, but your examples aren't).

Another possibility would be ~ものなら to indicate that achieving what you want might be difficult.

  • できれば、独立して事業を始めたい。 → Just a regular "if I can"
  • できるものなら、... → "If I really could (but I think it would improbable), ..."

Your answer is on the right track. What you are trying to say is indicative conditional vs. counterfactual conditional. – user458 Aug 17 '11 at 4:48

はい。同じ意味です。でも、"できれば、独立して事業を始めたい" はもっといいと思います。
