No, because your sentence contains no adjectives. "Researching", as an adjective, has the ability to *describe* the subject of the sentence, "I", in a phrase like "If I were researching". It is the adjectival description of the subject of a sentence that creates the impression of continuous activity (not any particular "tense") because the adjective can describe "I" as a "researching person". With no adjective, the subject is not described at all. Only verbs are present to state happens, will happen, or might happen, so no impression of continuity is created. Although "researching", as a present participle, is derived from a verb, it acts as an adjective, not a verb.

No, the sentence "If I researched this for three weeks, there would be a result." does not convey the same idea as the perfect continuous tense. This sentence follows a Type 2 conditional structure: If + past simple, would + base verb → It expresses a hypothetical situation in the present or future. However, to emphasize the duration of an action (as perfect continuous does), the correct structure would be: "If I were researching this for three weeks, there would be a result." → This uses past continuous ("were researching") to convey an ongoing action. If we wanted a perfect continuous structure (to emphasize how long something would have been happening), we would need a Type 3 conditional (for hypothetical past situations): "If I had been researching this for three weeks, there would have been a result." → This suggests the research was not done but would have led to a result.

Your sentence "If I researched this for three weeks, there would be a result." follows the Type 2 conditional structure, but it doesn't convey the idea of a continuous action over time as clearly as the Perfect Continuous would. To emphasize the duration of the action, you could say: ➡ "If I had been researching this for three weeks, there would be a result." (Type 3 conditional – focusing on a past hypothetical situation) ➡ "If I were researching this for three weeks, there would be a result." (Type 2 conditional – focusing on an ongoing hypothetical action in the present or future) The Past Perfect Continuous (had been researching) fits better for expressing a continuous action with a duration in the past, while the Past Continuous (were researching) works for an ongoing hypothetical action in the present or future. Tip: When talking about hypothetical actions with a specific duration, use Perfect Continuous for past situations and Continuous tenses for ongoing or future actions. This helps clarify whether the action is still happening or already completed.

Your structure describes an unlikely hypothetical. If I worked on this for three weeks, I’d get a result. (I’m not going to) If I work on this for three weeks, I’ll get a result. (I might) If I’d (I had) been working on this for three weeks, I’d (I would) have a result. (I haven’t been) If I’d worked on this for three weeks, I’d have a result. (I didn’t work on it. But it’s not as specific in terms of time as the above. It suggests that any three weeks of past work would have produced a result.)
